VerifySet throws TargetInvocationException when constructer refers to itself

[philiphoy]

The exception: System.Reflection.TargetInvocationException with the message " Exception has been thrown by the target of an invocation."

Is thrown during a call to VerifySet when code in a classes constructor references a property of this

Steps to Reproduce

This code reproduces the exception

       [TestMethod]
        public void Broken_moq()
        {
            var sut = Mock.Of<Example>();
            Mock.Get(sut).VerifySet(x => x.A = "A", Times.Never);
        }

        public class Example
        {
            public virtual string A { get; set; }
            public virtual string B { get; set; }
            public Example()
            {
                A = "";
                B = this.A;
            }
        }

Expected Behavior

The test above should run without throwing an exception

Invoking virtual members from a constructor is pretty much an anti-pattern.

There seems to be some support for that but I don't even know why supporting that (however imperfectly) would be a good thing, TBH.
